Constructing Journal week 3 Part 1: In this week’s tutorial, we visit four places in the campus and also observed their structure and material. Following is some information about those architectures. ERC Building

Potential Construction Constrains_ ERC was built between two old buildings Links to other buildings_ Steel Beams and Skylight ( glass) Construction type_ Steel Frame Construction

The highest place is approx 9m and the lowest place approx 6m

Structural System (s)_ Column Structure Materials_ Glasses, batten, steel, blue stone, concrete, plywood Other relevant comments_ Using the glass to be a skylight which can save electricity in the day time and this is to obtain sustainability. MSLE Building (Link Between Buildings) Potential Construction Constrains_

MSLE was built between two old buildings

Links to other buildings_ Concrete Structure

Construction type_ Stairs and wall: mass construction Roof: frame construction

Using a 1.8m hight person as unit, it approx 3.5 people which is 6.3m

Structural System (s)_ Cantilever Structure and beam structure

Materials_ Concrete, glasses, scam, zinc, stainless, steel, brick.

Other relevant comments_ The cantilever is the most special part in this building which is only depends on one side’s wall to offer the whole force to the cantilever. I also noticed that the cantilever used steel nails to stick itself on the wall.

Queens College Extention

Potential Construction Constrains_ An extention part where can expand the using area for this building. Links to other buildings_ It is still building now... Construction type_ Mass Construction

Approx 6.5m - 7 m

Structural System (s)_ Simple Structural System Column Structure Materials_ Timber, brick, concrete, granite, steel Other relevant comments_ This building’s original part using the steel truss to fixed roof which can be seen in the second pic.

Ormond Theology Centre Reception

Potential Construction Constrains_ This should be the extention part for the left side building. Links to other buildings_ Copper sheet Construction type_ Steel frame construction

Approx 6m--6.5m

Structural System (s)_ Less weight Materials_ Copper sheet, PVC down pile, Concrete(where include the timber inside), glass, steel, brick, stone. Other relevant comments_ The copper sheets make the steel pipeline not be easily broken.

Part 2: Task:

Our groups’ design:

Destroying Time: Group 1 :

Group 1 model is a triangle structure (Tension and Compression structure), which does firm and strong enough with the thick timber( 35×35), however the broken place is the thin timber (3×40 timber). And that thin timber deformed firstly then gradually broken. We can find material’s flexibility is important to a building. Group 2: Group 2 model seems not too firm and can be broken easily, the model’s labored point is only depend on the thick timber (35×35cm), so this structure makes the model only can obtain 7 rounds’ force from vertical side.

Group 3 (Our Group)

Our group’s model is very strong which obtains 12 rounds force from vertical. The wrong place in our designing is where we made “feet” under our span which made the vertical force can’t be standard and balance and finally dead. During our constructing, we used bench drill which help us decrease the time that we should spend and it does very helpful. On the other side, the method we setting the 3×40 timer is put it vertically, because when a force coming vertically, then the timber can bear a maximum force to against it, and this is the success point!
